Neither did many varieties of "Steel" fare so well as either the laminated steel or Whitworth barrels. As I recall though few if any were so bad as to be considered "Dangerous".
The Parker G grade barrel which took on the order of 30K psi to burst was neither Whitworth fluid or Birmingham Laminated.
It was almost of a certainty made of Belgian Damascus.
Assuming the walls did not become too thin with the chamber lengthening, & with that weight of gun it's highly unlikely, I would have absolutely no qualms about shooting that 1 oz load @ 1060 FPS through them.
